Definitions
- the present invention relates to a ball joint according to the preamble of claim 1.
- the sliding fabric consists of fibers made of plastic with low friction, for example polytetrafluoroethylene.
- the fiber material is surrounded by the plastic bearing shell and is inserted into the recess in the ball joint housing.
- the fibrous sliding fabric is relatively strongly compressed under pressure.
- the ball is therefore not very rigidly mounted in the ball joint housing and can give way particularly when subjected to greater pressure.
- the object of the present invention is to develop a ball-and-socket joint of the type mentioned so that the ball-and-socket joint can withstand a high pressure load without giving in in the pressure direction, in order to avoid an inadmissible play.
- the invention has the particular advantage that the sliding fabric is firmly anchored in the bearing shell on the one hand so that it cannot slip. Nevertheless, the very smooth internal surfaces of the sliding fabric lie directly on the ball and ensure a good sliding bearing even under high pressure loads, especially since the material of the bearing shell penetrating the sliding fabric also acts as a further support and sliding surface.
- Fig. 1 shows a ball joint according to the invention of the
- Fig. 2 is a view according to section I-I of Fig. 1 and Fig. 3 shows a ball joint of another embodiment of the
- a ball joint designates a ball joint according to the invention. It has a ball joint housing 2 with a recess 3 into which a ball 4 of a ball pin 5 is inserted.
- the ball 4 is surrounded by a sliding fabric 6.
- This sliding fabric 6 is chosen to be permeable in such a way that when material is injected for a bearing shell 7 through a sprue 8 in the ball joint housing 2, the injected material penetrates the sliding fabric 6 and reaches up to the ball 4.
- the sliding fabric 6 is very firmly anchored in the bearing shell 7, so that it cannot slip or move under load. Nor can it be compressed under pressure, since the material of the bearing shell 7 reaches as far as the ball 4 and additionally acts as a support and sliding surface.
- the sliding fabric 6 is designed as a network 6a.
- This network 6a is designed in such a way that outer threads 6.1 running in one direction and inner threads 6.2 running in the crossing direction are arranged in two adjacent planes and the threads 6.1 and 6.2 are integrally connected to one another at the crossing points 6.3.
- the network 6a is further designed so that it encloses the ball 4 relatively tight.
- the inner threads 6.2 are preferably at least partially, but preferably completely, pretensioned against the ball 4.
- the ball 4 provided with the net 6a is inserted through a correspondingly large opening 2.1 of the ball joint housing 2 into its recess 3.
- the inwardly crimped upper edge region 2.2 of the ball joint housing 2 overlaps the net 6a and the ball 4 and lies against a tool part 9.
- the recess 3 is dimensioned so that first the sliding fabric 6 or mesh 6a and then the ball 4 can be used.
- the recess 3 is designed so that the outer threads 6.1 rest against the inner wall 3.1 of the recess 3 in whole or in part, so that the ball 4 is fixed in the correct position.
- the material for forming the bearing shell 7 is injected, it is distributed over the net 6a and penetrates up to the spherical surface 4.1.
- the outer threads 6.1 as long as they do not rest against the inner wall 3.1, are completely molded in.
- the inner threads 6.2 are also reshaped, but the area lying against the spherical surface 4.1 remains free and thus serves to slide the spherical surface 4
- the ball pin 5 with the ball 4 and net 6a is fixed in position from the outside by a suitable device.
- the position can be fixed, for example, by a molding tool 9 necessary for injecting the bearing shell material.
- the opening 2.1 is so large that the ball 4 can be used together with the network 6a.
- the upper edge region 2.2 is then flanged inwards.
- the ball 4 is centered in the recess 3 with the net 6a and fixed in the correct position, possibly with a slight prestress.
- 6.3 in turn denotes the crossing points between the outer and inner threads 6.1, 6.2.
- the bearing shell 7 is then produced in the manner already described. The injection can take place through the lower sprue 8 and / or one or more lateral sprue 10.
- the marginal edge 2.3 is flanged inwards to such an extent that it bears against the bearing shell 7.
- the mesh 6a or the sliding fabric 6 and the bearing shell 7 advantageously consist of a linear or crosslinked elastomer, in particular of polyurethane, polyethylene, polytetrafluorocarbon, such as polytetrafluoroethylene, polyamide, polyimide or a mixture of at least two of these materials.
- the materials provided for the sliding fabric 6 or the mesh 6a have a low coefficient of friction, preferably in the range from 0.05 to 0.4.
- the sliding fabric 6 can also be designed as a textile fabric with smaller fabric openings if the plastic material used for the bearing shell 7 to be produced is correspondingly thin.
